Consider a hypothetical compound composed of elements X, Y, and Z with the empirical formula X2YZ3. Given that the atomic masses of X, Y, and Z are 41.2,
57.7, and 63.9, respectively.
A. Calculate the percentage composition by mass of the compound. If the
molecular formula of the compound is found by molar mass determination to be
actually X4Y2Z6.
B. What is the percentage of each element present? Explain your results.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
